3.1 Precautions

3.1.1 Mount the station protector so as to minimize the
possibility of dirt or moisture getting into the protector.

3.1.2 Station protectors mounted side-by-side or end-to-end
should be placed so covers can be easily removed.

recommended that a protected building terminal in an interior
terminal box be installed in place of station protectors.

using appropriate hardware (the length of the mounting screws
should allow for 1/8” of length within the protector.
